Milling feed rate mysteriously changes

Recommended Posts

Hello. I am extremely new to Mastercam, so forgive me if I don't make a lot of sense. I am working on a lathe part that also requires multi-axis milling. I've been tackling it for quite some time now. It is very important to note that I am doing this for work and on a company laptop. Said laptop is also being used by other programmers, for other machines (I am trying to program this part for an OKUMA.)
When I tried to post my G-code yesterday, I noticed that the feeds for the multi-axis milling portion of the job had drastically changed. I am talking a difference of about 100-150 (I am not quite sure where to see what the units are). I did not make any changes to the program, I even tried posting the code from a similar (almost identical) project that I know was using the correct feeds before. Same thing happened.
My theory is that one of the other programmers made a change to the software that I am not aware of. The code, however, seems to be ok- seems to be generated for OKUMA.
Any ideas?

That is called inverse time and on certain machine required to allow the Multiaxis toolpath to work correctly. If your machine has TCP abilities and can take all the kinematics of the machine into account then the different feedrates are not needed. Reach out to your dealer and see how was the post configured for the machine and they can help you dial it in.
